Possible disadvantages

  • Steep Learning Curve
    New developers might find Play’s reactive model and functional programming concepts challenging, especially if they are primarily experienced with traditional web frameworks.
  • Memory Usage
    Play applications can be memory-intensive, which might lead to higher hosting costs compared to lighter frameworks, especially for smaller applications.
  • Complex Configuration
    Setting up and configuring a Play application can be complex and time-consuming, particularly for beginners or small teams without extensive experience.
  • Limited Community Support
    Although Play has a dedicated user base, its community is smaller compared to more popular web frameworks like Spring or Django, potentially making it difficult to find solutions and community-driven resources.
  • Verbose Code
    Play applications may require a significant amount of boilerplate code, particularly when integrating with other services or libraries, leading to potentially verbose and less maintainable codebases.

Questions & Answers

As answered by people managing Play Framework and Jaah.

How would you describe the primary audience of your product?

Jaah's answer:

Engineering leaders, teams and solo developers who want to hand real work to AI agents without lowering the bar for what reaches production: teams that care about review, security, governance and keeping code on their own infrastructure.

What makes your product unique?

Jaah's answer:

Jaah doesn't just generate code; it gets code to production. Every task runs through a staged pipeline and comes back as a pull request that has passed your own tests plus code, security and acceptance review, corporate guardrails, with a report showing the evidence for each acceptance criterion, everything is auditable.

Why should a person choose your product over its competitors?

Jaah's answer:

Coding agents are cheap; trusting their output is the hard part. Jaah carries your standards into every repository, enforces branch protection agents cannot bypass, and keeps every action on record.

What's the story behind your product?

Jaah's answer:

Jaah (Just Another Agentic Harness) was built by its own agents, running in its own harness, on tasks its own pipeline handed them, and it still is. Every change to the product is worked by the same pipeline it sells, under the same reviews, and merged the same way. But at its origin it was devised by a team who started to be cognitively overloaded by all the AI agents it was running.

Which are the primary technologies used for building your product?

Jaah's answer:

Python, Typescript, React, Postgres, but Jaah can rewrite itself into any other stack in a few days.

  • Examples of CompletableFuture-based APIs / state of async in Java?
    I can see the Play framework really leans into async, and only tolerates blocking controllers. What else is out there? Source: about 3 years ago
